Andes UART is compatible with uart8250 driver. We can use
fdt_serial_init() as platform console init hook.
dts example:
serial0: serial@f0300000 {
compatible = "andestech,uart16550", "ns16550a";
reg = <0x00000000 0xf0300000 0x00000000 0x00001000>;
interrupts = <9 4>;
interrupt-parent = <&plic0>;
clock-frequency = <19660800>;
current-speed = <38400>;
reg-shift = <2>;
reg-offset = <32>;
reg-io-width = <4>;
no-loopback-test = <1>;
};
